摘　　要：建立速率方程模型对高功率Tm:YAG激光器的输出特性进行了模拟计算,与不同温度及输出率条件下激光输出特性试验结果进行了对比和分析。理论模拟与实验较好吻合表明理论模型能较好地模拟Tm:YAG激光器输出特性;模拟结果表明温度升高极大影响激光输出效率。Tm:YAG激光器可实现大能量调Q脉冲输出且脉宽可通过损耗大小调节,满足不同应用需求。The analog computation of output characteristics of high-power thulium laser was carried out through establishing rate equation model. Comparison and analysis have been done between output characteristics of different temperature and output rates. The results that theoretical simulation is consistent with experiment indicate the theoreti- cal simulation can well simulate laser characteristics. Simulated results show that temperature rising has a large impact on laser output efficiency. Tm：YAG laser can achieve high energy of Q-switching pulsed output and the pulse width can be adjusted by power loss which can meet different utilization.
